Application led April 2, 1909. Serial No. 487,450.

To all whom it may concer-n:

Be it known that I, GEERT Moulin, a citizen of the United States of America, residing at Zeeland, in the county of Ottawa and State of Michigan, have invented cert-ain new and useful Improvements in Silos; and I do hereby declare'the following to be a full, clear, and exactr description of the invention, such as will enable others skilled in the art to whichit appertainsv to make and use' the same. I

My invention relates to improvements in silos, and more particularly to the doors and adjacent parts thereof, and its object is to*- providel the same with various new and usc'' ful features hereinafter more fully described and "particularly pointed-out inthe claims, reference being had to the accompanying drawings, in which: v

Figure 1. is a front elevation of a portion of a silo embodying my invention; Fig. 2. is.

a vertical section of the same on the line 2 2 of Fig. l.; Fig. 3. isa horizontal section of the same on the line 3-1-3 of Fig. l.; Fig. 4. the same on the line 4 4 of Fig. l.

Like numbers refer to like parts inall of the figures. l represents a portion of the body of the silo, preferably made of vertically disposed staves joined 'to each other by tongue and groove at their edges. This structure is surrounded by hoopsor bands 2, preferably of round rod provided with any convenientmeans of tightening the same'l (not shown) The staves are spaced' apart 'to form-a door opening wherever convenient and across this openlng at regular intervals corresponding to the intervals of the hoops or bands, are horizontal braces having an outer' surface concentric with the axis ofthe structurev and of somewhat greater radius to project outward therefrom a convenient distance, and Vin this outer surface is a deep groove 3Q to receive the respective band. These braces overlap the adjacent staves at the outer side and are secured thereto by bolts 4 and between the stavesthe Vbraces extend inward to the innersurface of the structure and are connected to the staves by tongues and grooves 11 and l2, wherebythe adjacent edges of the staves are securely held and connected to the braces, and therbraces also held thereby.

, The inner sides of the braces `a're preferably rectilinear and the braces are beveled inward to iit the beveled upward and lower' edges ofthe doors.` The respective doors consist of a seriesof strips, preferably three as shown, but any v4number may be used, joined. to' each otherI with tongues and Staves in like manner, as at l1 and 12. These tongues and grooves are preferably semicircular in cross section, whereby these strips will swing freely into and out of engagement upon hingesG-connecting them to each other in series The door is also hung to ,swing inwardly upon vop'positely arranged hinges 6a at one sideof the opening and supporting the v'door upon anV adjacent stave. The middle stripl fastening' consistlng of a cam inclined to the surface of the door and eccentrically pivoted at 9 to the same, and also adapted to swing into a ,recess in the underj side of the brace bar 3, bymeansof a lever 10, thus being protected .from the weather by the overhang- 'ing brace-bar and prevented from cloggin@ by snow or ice.; Each door is also provide l with a horizontally disposed handle 7 which is available-to'closethe door and also useful in climbing upon the outside of the structure by. meansof these brace bars as foot holds-"M1 1` What'Ixclaim is: j v

1. Asilo, comprising staves spaced apart to forma door opening, braces at intervals across. saidopening, and doors between 'said braceseach consisting. of a series of, strips hinged to eachother, said strips also joined to each other and ',tothe adjacent staves by tongues 'and grooves, and means for securbra'ces and stav'es. j 4 j v 2.l A silo, 'col'nprising vertically4 disposed .st'aves joined-'to eachother by tongues and grooves andspaced apa-rt to form a door opening, braces at intervals across said opening, and beveled'at the ,upper and under sidesto receive the doors, doors between the braces, each 'consisting of -three separate strips hinged to each other and one side strip. hingedto the/adjacent stave, said strips also being joined to each other and .to the'adja'cent staves by4 detachable tongues and grooves andl a' fastening and handle on the middle strip.

3. A silo, comprising vertically disposed staves joined by' tongues and grooves and 'spaced apart ,to form a door opening, brace bars at intervals across said opening and extending between adjacent staves' `and grooves, and also --joined to the adjacent is also provided with a ing the4 ,doorslinl closed positionbetween the joined thereto by tongues and grooves and also overlapping on the outside of said and a groove inthe outer side, bands surrounding the staves and extending through said grooves, doors between the braces, each consisting of a. series of separate strips hinged to each other and joined to yeach other and to the adjacent 'stoves by tongues 1f and grooves and beveled at the end to`t the signature GEERT MOEKE.
